Technical Field

[0001] This utility model relates to the field of power equipment technology, specifically a DC power distribution cabinet. Background Technology

[0002] DC switchboards are key equipment in DC power supply systems used for power distribution, control and protection. They are widely used in photovoltaic power plants, communication base stations, data centers and other scenarios. Their main function is to distribute the input DC power to each load circuit and to protect the circuit from overload, short circuit and other damage.

[0003] However, existing DC distribution cabinets have some problems during use: First, the grounding mechanism is fixed and cannot be adjusted. When the installation ground is uneven or there is a height difference, the grounding terminal is difficult to contact the ground, affecting the grounding effect. Second, after the distribution cabinet is moved, relying solely on the roller brakes is insufficient to ensure stability, and it is prone to displacement due to external collisions, posing a safety hazard. To address these issues, there is an urgent need for innovative design based on the existing DC distribution cabinets. Utility Model Content

[0004] The purpose of this utility model is to provide a DC power distribution cabinet to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a DC power distribution cabinet, comprising a DC power distribution cabinet body, a cabinet door installed on the front side of the DC power distribution cabinet body, and rollers provided at the four corners of the bottom of the DC power distribution cabinet body, anti-movement mechanisms provided at the front and rear ends of the bottom sides of the DC power distribution cabinet body, and grounding mechanisms that adapt to different ground heights provided on both sides of the bottom of the DC power distribution cabinet body.

[0006] Preferably, the grounding mechanism includes through holes. Through holes are provided on both sides of the bottom of the DC distribution cabinet body.

A handle is fixedly attached to the upper end of the movable rod inside the DC distribution cabinet body. Through holes are provided inside both the handle and the movable rod. One end of a conductive wire is fixedly attached to the top of the grounding terminal. The other end of the conductive wire passes through the through hole and is fixedly connected to the bottom of the DC distribution cabinet body. A vertical plate is fixedly attached to the bottom of the DC distribution cabinet body. A horizontal plate is fixedly attached to the top of the vertical plate. The outer side of the movable rod is in contact with the inner side of the horizontal plate. A spring is nested on the outer side of the movable rod. A fixing ring is nested and fixedly attached to the outer side of the movable rod below the horizontal plate. The spring is located between the horizontal plate and the fixing ring. A fixing mechanism is provided between the fixing ring and the vertical plate.

[0007] Preferably, the fixing mechanism includes a groove, a groove is provided on one side of the vertical plate, a slot is provided at the bottom of the deepest part of the groove, one end of a locking block is engaged inside the slot, and the other end of the locking block passes through the inside of the slot and is fixedly connected to the outer wall of the fixing ring.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-6 This utility model provides a technical solution: a DC power distribution cabinet, including a DC power distribution cabinet body 1, a cabinet door 2 installed on the front side of the DC power distribution cabinet body 1, and rollers 3 are provided at the four corners of the bottom of the DC power distribution cabinet body 1. Anti-movement mechanisms are provided at the front and rear ends of the bottom sides of the DC power distribution cabinet body 1, and grounding mechanisms that adapt to different ground heights are provided on both sides of the bottom inside the DC power distribution cabinet body 1.

[0023] The grounding mechanism includes through holes 4. Through holes 4 are provided on both sides of the bottom of the DC distribution cabinet body 1. The inner wall of the through holes 4 is fixedly connected to the outer wall of the rubber sealing sleeve 5. A movable rod 6 is slidably installed through the inside of the rubber sealing sleeve 5. A grounding terminal 7 is fixedly attached to the lower end of the movable rod 6 below the DC distribution cabinet body 1. A handle 8 is fixedly attached to the upper end of the movable rod 6 inside the DC distribution cabinet body 1. Through holes are provided inside both the handle 8 and the movable rod 6. One end of a conductive wire 9 is fixedly attached to the top of the grounding terminal 7. The other end of the conductive wire 9 passes through the through hole and is fixedly connected to the bottom of the DC distribution cabinet body 1. A vertical plate 10 is fixed, and a horizontal plate 11 is fixed to the top of the vertical plate 10. The outer side of the movable rod 6 is in contact with the inner side of the horizontal plate 11. A spring 13 is nested on the outer side of the movable rod 6. A fixing ring 12 is nested and fixed below the horizontal plate 11 on the outer side of the movable rod 6. The spring 13 is located between the horizontal plate 11 and the fixing ring 12. A fixing mechanism is provided between the fixing ring 12 and the vertical plate 10. This grounding mechanism, through the sliding of the movable rod 6 and the elastic force of the spring 13, allows the grounding terminal 7 to flexibly adapt to different ground heights, ensuring the grounding effect. At the same time, the rubber sealing sleeve 5 can prevent dust and moisture from entering the cabinet. The concealed arrangement of the conductive wire 9 avoids messy wiring.

[0024] The fixing mechanism includes a groove 14. A groove 14 is provided on one side of the vertical plate 10. A slot 15 is provided at the bottom of the deepest part of the groove 14. One end of a locking block 16 is engaged inside the slot 15. The other end of the locking block 16 passes through the inside of the slot 15 and is fixedly connected to the outer wall of the fixing ring 12. A certain distance is reserved between the end of the locking block 16 inside the slot 15 and the deepest part of the slot 15, so that the end of the locking block 16 can move inside the groove 14 and the slot 15 during rotation. Through the cooperation of the locking block 16 with the slot 15 and the groove 14, the fixing and unlocking of the movable rod 6 can be quickly realized, and the operation is simple.

[0025] The anti-movement mechanism includes fixed blocks 17. Fixed blocks 17 are fixed to the bottom and front and rear ends of both sides of the DC distribution cabinet body 1. A screw rod 18 is installed through the thread inside the fixed block 17. A support plate 19 is fixed to the lower end of the screw rod 18. An anti-slip rubber sheet 20 is fixed to the bottom of the support plate 19. The support plate 19 is driven to rise and fall through the thread transmission of the screw rod 18, which can stably support the distribution cabinet and prevent it from moving. The anti-slip rubber sheet 20 increases the friction with the ground, further improving stability. The symmetrical distribution of the fixed blocks 17 makes the support force uniform.

[0026] The support plate 19 is designed as a frustum structure. The frustum structure of the support plate 19 increases the contact area with the ground, disperses the pressure of the DC distribution cabinet body 1 on the ground, and can maintain stability on uneven ground, while enhancing the anti-tipping ability of the support.

[0027] Tightening plates 21 are fixed on both sides of the top of the lead screw 18. The tightening plates 21 provide a convenient force application point for rotating the lead screw 18. The height of the support plate 19 can be easily adjusted without the need for additional tools, saving time and effort and making it suitable for operators to quickly complete the fixing operation.

[0028] Working principle: When using this DC distribution cabinet, first move it to the installation position using the bottom rollers 3. Then, rotate the screw plate 21 in the anti-movement mechanism, which drives the lead screw 18 to move downward within the fixed block 17, so that the anti-slip rubber sheet 20 at the bottom of the support plate 19 is in close contact with the ground until the DC distribution cabinet body 1 is firmly supported and prevented from moving.

[0029] Next, perform the grounding operation. Pull handle 8 upwards, and the movable rod 6 slides upwards within the rubber sealing sleeve 5. The fixing ring 12 rises accordingly and compresses the spring 13. At this time, the locking block 16 disengages from the slot 15 and enters the groove 14. Rotate handle 8, causing the movable rod 6 and the fixing ring 12 to rotate, moving the locking block 16 to the appropriate position within the groove 14 to release the lock. After releasing handle 8, the spring force of spring 13 is released, pushing the fixing ring 12 downwards, which in turn causes the movable rod 6 to slide downwards along the rubber sealing sleeve 5, bringing the grounding terminal 7 into contact with the ground.

[0030] Since the length of the movable rod 6 is fixed, its telescopic adjustment function is mainly achieved through the elastic deformation of the spring 13: when there is a bulge in the ground, the grounding terminal 7 is pressed and pushes the movable rod 6 to move slightly upward, and the spring 13 is further compressed and stores elastic force; when there is a depression in the ground, the elastic force of the spring 13 pushes the movable rod 6 to move downward, ensuring that the grounding terminal 7 is always in close contact with the ground, thereby adapting to different ground heights.

[0031] Conductive wire 9 forms a conductive path through the through holes in the movable rod 6 and handle 8, connecting the interior of the DC distribution cabinet body 1 to the grounding terminal 7, ensuring a continuously unobstructed grounding circuit. Rubber sealing sleeve 5 tightly wraps around the movable rod 6, maintaining a sealed state throughout its up-and-down sliding process, effectively preventing dust and moisture from entering the cabinet through the through hole 4, thus protecting the operating environment of the electrical components inside the cabinet.

[0032] When the distribution cabinet needs to be moved, pull the handle 8 upwards, the movable rod 6 slides upwards, the grounding terminal 7 separates from the ground, and at the same time the fixing ring 12 compresses the spring 13. Then rotate the handle 8 to drive the fixing ring 12 and the locking block 16 to rotate, so that the end of the locking block 16 moves into the groove 14 until the end of the locking block 16 is above the slot 15. Release the handle 8, and under the elastic force of the spring 13, the locking block 16 moves downwards and engages with the slot 15, so that the grounding terminal 7 is suspended and fixed, ensuring that the grounding terminal 7 will not affect the normal movement of the DC distribution cabinet body 1.

[0033] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
